Hi guys for those of you who know me ... I'm Sir-Maddoc ....
well yesterday I see a topic at our thundermods forum which was called "Generals und das Wasser" here you can see some pics out of the topic ...

But you see the problem, the height. So far I couldnt figure out how to get it right but perhaps some good moders here have an idea
You should thank Ingoneur who found it out
